1、 Features of fixed pneumatic ball valve:
1. Double blocking and discharging function: the fixed pneumatic ball valve uses the spring to pre tighten the floating valve seat. No matter the valve is in the fully open or fully closed state, the valve seats at the upstream and downstream sides block the fluid, and the residues in the cavity of the valve body are discharged through the discharge valve.
2. Automatic pressure relief function: in case of abnormal pressure rise caused by the temperature rise of the medium staying in the valve body cavity, it is not necessary to pass through the safety valve, but only the valve seat function can automatically relieve pressure, which is very important to ensure the safety of the valve when delivering liquid medium.
3. Fire safety structure: all valves have fire safety functions, and their design and manufacture comply with API 607 and API 6FA specifications.
